Reflectance Fiber Optic Probe FSTT-04

Optical Path Length: 2/10/20/Custom Optical fiber material: UV silica fiber Fiber connector: SMA905

A reflective fiber probe is a measurement sensor that guides light to a target surface and collects the reflection for an instrument. It enables measurements where physical access is restricted or environments are harsh. Unlike the source's 'radiative (diffuse-reflectance)' probe, it is better suited to smooth, bright, or highly reflective surfaces. Working principle: 1. A source such as an LED or laser sends light through a fiber to the target. 2. Light reflects from the surface. 3. A receiving fiber adjacent to the transmitting fiber collects the reflection. 4. An instrument such as a spectrometer analyzes intensity, wavelength shifts, and other properties to determine surface information. Design considerations: 1. Sensor-target distance must suit the application for appropriate reflectance and signal quality. 2. Packaging must address chemical resistance, waterproofing, vibration resistance, and other environmental requirements. 3. Plastic, glass, or special alloys may provide the required chemical compatibility and mechanical strength. 4. Suitable sources/detectors must match the spectral range and reflectance. Such probes suit precise noninvasive measurements, especially when direct contact is difficult or impossible, such as on rapidly rotating shafts or under unusual temperatures. Selection/design parameters: 1. Numerical aperture (NA) determines light acceptance. Larger NA captures more reflected light and increases signal but may reduce resolution. 2. Working distance must be close enough for adequate collection but far enough to avoid contact or thermal damage. 3. Probe diameter/configuration determines physical fit and projected/received beam size at a given distance. 4. Fiber material/bend radius must provide chemical resistance and safe bending without damage. 5. Probe and connected LEDs, lasers, spectrometers, and other equipment must be optimized for the desired spectral range. 6. Consider temperature, humidity, chemical exposure, impact, and pressure. 7. If lenses or focusing elements are included, choose focal length for the operating distance and resolution. 8. Source type must match probe design, brightness, and wavelength requirements. 9. Transmitting/receiving fiber arrangement determines coupling efficiency and how much reflected light is collected. 10. Signal amplification, filtering, and processing are essential; electronics must handle the returned signal. 11. Some applications require high mechanical strength against loads or impacts. 12. Fiber end-face treatment, such as polishing, affects reflectance and measurement accuracy. Evaluating these parameters helps select or design an appropriate reflective probe for the required application performance.
